Thanks. Take me a long time to reproduce your bug. In your description you missed that the bug is present when we use a mouse click. Also if you use the following scenario – evarthing work ok.
1. Click on cell with content Yes
2. Change the value from checked to unchecked
3. Press Enter to save it
evarthing correct.
But this not work (bug)
1. Click on cell with content Yes
2. Change the value from checked to unchecked
3. “CLICK ANOTHER CELL”
Also the problem is not in grid.common.js, but in grid.celledit.js
